HAL is not used by Xorg for output devices or any other devices, only input.

Versions that do not use HAL

Since the HAL project has stopped development and deprecated itself, X.Org is planning to move off HAL in the future. Support for udev instead of HAL is available in X Servers 1.8 and later and enabled by default, pending platform availability. As HAL was also used for input device configuration, a new feature has been added to X Server 1.8 to support configuration snippets in the xorg.conf.d directory. Instead of udev rules, users and distributions are encouraged to use the xorg.conf.d for configuration. Old-style xorg.conf configuration is still available.

Neither DeviceKit, nor the udisks/upower/etc. replacements provide any of this functionality for input devices, and the DeviceKit authors have indicated that they do not plan to provide such functionality, suggesting direct use of the OS interfaces such as libudev instead.
